Research areas:

  • Improvement of culture and post-harvest pond bottom soil and water quality.
  • Carbon sequestration through biochar from pond sediment sludge.
  • Hydrogeochemical characterisation of inland saline waters and their suitability for aquaculture
  • Seasonal variation in carrying capacity of brackishwater sources for shrimp aquaculture.
  • Antibiotic degradation pathways and kinetics in the aqueous system.

 

Brief profile:

After taking Masters in Soil Science and Agricultural Chemistry in 2005 and PhD in Soil Science and Agricultural Chemistry in 2015 I am working in CIBA since 2013 on “Treatments for improvement of pond bottom and water quality. I currently work in division of Aquatic Animal Health and Environment Division in CIBA. I have worked on oxiding agents for enhancing the organic matter degradation, environmental monitoring of shrimp and fish farms.I have contributed to development of improved methods of pond preparation. I have interests in pond bottom sediment quality improvement by Advanced Oxidation Technology. Pond water quality management by biopolymer based adsorbents and ion exchange materials. Efficient and economic utilization of sludge by converting to biochar and use it as amendment for removal of nutrients from discharge water.

No Title Funded By
1 To develop and evaluate the treatments for pond bottom and water quality improvement. Institute
2 National Innovations in Climate Resilient Agriculture (NICRA)  ICAR
3 All India Network Project on Fish Health ICAR
